The types of power cables are as follows:
single strand
Two majors
Three strands
Four strings
Five courses
Power cables have different types in terms of pressure type and voltage level, which are:
Cable with high pressure type
Cable with super strong pressure type
Medium pressure type cable
Cable with weak pressure type
To answer the question of what is a power cable, it is better to know the most important internal parts of a power cable, which are as follows
Power cable conductor
Usually, this type of cable is made of aluminum or copper. The task of the conductor of this type of cable is to pass electric current.
Cable insulation
It is used to protect the cable conductor.
Cable shield
The shield of the cable is located on the insulation surface and it is in the following types: strip wire and mixed.
Cable armor
One of the most important parts of a power cable is the cable armor, whose task is to protect the cable against mechanical stress.
The final cover of the cable
The cable cover is responsible for the protection of all the layers of the cable and the cable specifications are also included on it.
The internal structure of the power cable
Among the uses of power cable, the following can be mentioned:
Installations that can be installed in the mobile connection tray due to its high flexibility
Industrial facilities and buildings, etc. Industrial facilities and commercial buildings
Power cable applications
In order to maintain and use properly and increase the life of the high voltage cable, the following points should be taken into account:
Cabling of this type of plastic cable should not be done in winter, but if this type of cable is used in winter, the cable reel should be heated in a room first and then used immediately. In case of using this type of cable, In the soil, it should be dug in a 70 cm hole, and after placing the cable in the hole, 20 cm of soft soil should be poured on it and bricks should be placed on it, and finally, the inside of the hole should be filled with normal soil.
When installing this type of cable, its bending radius should not be less than 12 to 15 times its outer diameter
